After you had made your original comment about shrinking the root filesystem, I did some destructive tests, simply ripping out as many documentation-oriented packages as seemed likely candidates, using aptitude on your distribution in a running BBB. I didn't touch the compilers or -dev libraries. I didn't keep good notes but it looked like doing just what I did reduced the filesystem nearly 1GB (I didn't see if what I had left would actually fit into the 2GB flash). The next time, I'll be more methodical and keep better notes.
